The 4th BCT Training Exercise support was conducted during the period 6-24 July 1998 at the Close Combat Tactical Trainer (CCTT) facility, Ft. Hood, TX. The exercise was sponsored by the Directorate of Training, Doctrine and Simulation (DOTDS), U.S. Army Aviation Center, Fort Rucker, AL. The training exercise utilized virtual simulation (CCTT and BICEP) integrated with a notional tactical command and control network to provide training for 4th BCT task force. A notional AVTOC was integrated on a tactical LAN. A DIS LAN consisted of manned simulators (ground and air elements) and computer generated forces. The two LANs were connected via the Tactical Simulation Interface Unit (TSIU). Scenarios were utilized to exercise the ground elements, aircrews, and command and control processes. The virtual stations included the Aviation Reconfigurable Manned Simulator (ARMS) proof of principle device and follow-on units (BICEP), the CCTT modules (tanks, and fighting vehicles). This exercise report addresses the simulation, tactical, and communications networks developed to support the integrated exercises and lessons learned. This document does not address the performance of the 4th BCT Task Force during the exercise.
